known in the art as monogram indica-l The register to which the indicating device may be attached may be of any well known type but as here shown, a two motion machine is used. Banks of keys serve to determine the position of differentially movable segments which are geared positively to a usual type of cylinder indicators having numbers on their peripheries. Themain operating shaft, to which may be atto operate the mechanism and thereby differentially to position the said drum indicators. Each indicator cylinder is provided with a switch arm arranged to move over a series of contacts which are connected through cables to the distant indicator and serve to control its operation.

The form of monogram or changeable indicator shown is well known at present an the lamps are separately wired as shown in Fig. 2 to a series of pairs of fixed contact points. Adapted to co-act with these contact points are rotating disks having projections such as are shown in Fig. 6 and which serve to determine which of the lamps shall be lighted.

A motor is provided for rotating the contact disks of the distant indicator. This marked with a like letter on motor is arranged to drive said disks by a belt. When the motor starts the series of contact disks are depressed to an extent sufficient to break the lamp circuit and are then rotated by the motor until stopped by solenoids, which are under the control of the register indicating drums, and the operating current for which is supplied by the magneto. The magneto is driven by the said motor so that the current is only furnished in cables from the register to the distant indicator While the indicator is being operated. The circuit for the motor is controlled by the main operating shaft of the The motor however is .arranged to break its own circuit at the end of the operation, thereby insuring a complete operation of the motor and consequent complete setting of the disk contacts. 3

Referring more particularly to the drawings. In Fig. 1 is shown a side elevation of one bank of keys of a cash register with an indicating drum 7 for said bank and a differentially movable caring controlled by the bank. The drum is revoluble with the difierentially movable gear 8 and has secured theretoa switch arm 9. In the path of the switch arm 9 is a series of contacts 10 corresponding to the numerals on the indicator drum 7. These contacts are each connected by separate wires to corresponding solenoids 11 in the distant indication device. (Figs. 2' and 3). The solenoids 11 the revoluble contact are used to control of a revolution, the

control the lamp indimembers 12 which 28. A cam cators 13. The 'revoluble contact members 12 through a belt connection 1 1 are operated by a small motor 15, which may be in the regular light circuit with the lamps of the distant indicator. The motor 15 also serves to operate a small magneto 16 which supplies current to the small switch controlling solenoids 11 by means of wires 17' and 18.

Each denomination of the distant indicators is provided with a contact member 12. These contact members consist of a series of disks 19 rigidly mounted on revoluble shafts and connected by a wire 24: to form one solid conductor. Each denomination of the indicators is provided with 28 lights arranged as shown in Fig. 5. illustrating, each lamp is marked with an individual letter and its corresponding fixed contact 23 to which the lamp is wired is Fig. 2. The fixed contacts are arranged at the side of the revoluble contact member 12 as shown in Fig. 2. Fig. 2 also shows the wiring between the fixed contacts and the lamps of one denomination of the indicators. lof said lamps have a common return wire 21. There are 14 of the disks 19 comprising each of the contact members 12 and each of said disks are provided with the right number of contact extensions to provide for thelighting of one or both of two of the lamps of the indicator when either of said lamps are needed in forming any numeral. It will be seen from the arrangement of the contacts in Fig. 6, that if the disks were in contact as shown in Fig. 6, the figure 0 would be lightedv at the indicator; if said disks were turned one tenth of a revolution to the right, the figure 1 would be lighted at the indicator; if they were turned two tenths figure 2 would be lighted, and so on to nine'tenths when the 9 is lighted. These contacts 19 are arranged one above the other as shown in Fig. 6.

As stated above the members 12 are constructed to form a solid conductor. Two

'extra disks 19 are provided for the member 12, which disks, in all positions of the member, coiiperate with two fixed contacts similar in form to the fixed contacts 23. i To these fixed contacts is connected the common return wire for' the circuits of all the lamps of the indicator appropriate to the member 12. In the present instance two disks 19 For convenience in and fixed contacts 23 are provided merely Y for the purpose of forming a, more reliable contact for the common return. It will, however, be readily seen that this number is not essential as one or tacts would work equally as well.

The motor switch 25 is controlled by the main operating shaft 26 of the cash register by means of a switch 27 and a local circuit 29 rigid with the shaft 26 closes more disks and con- I a lateral extension 79, which extension is makes a complete revolution. The main operating handle is secured to the shaft 26 and is operated as usual after the amount keys have been depressed. When the circuit 28 is closed a solenoid 30 of the distant indication device which is included in said circuit 28 (Fig. 2) becomes energized and draws down its armature 31 and the arm 32 which is connected to the arm 31, and pivoted to the frame of the distant indication device at 33. The movement of the arm 32 carries the pin 47 thereon from over the flange on the spring pressed arm 34. The arm 34 is rigidly mounted on a shaft 70, which shaft, under the influence of spring 71, has a tendency to turn, thereby raising the arm 34, but such movement is normally revented by reason of the engagement of the outer end of said arm with the pin 47 mounted on the upwardly extending arm 32, as above de scribed. Also rigidly mounted on shaft 70 is a downwardly extending arm 35, the lower end of which oroiects in the path of a plate 72 mounted on the side of a cam disk 36, having the camming shoulder 83. The disk 36 is mounted to turn loosely on shaft 37' and is further provided with a pin 74 and elongated slot 75 through which slot pro.- jects a pin 76 mounted on a companion disk 77 which disk is rigidly mounted on the shaft 37. A spring 781 is wound about said shaft 37 and the ends of said spring are attached to the pins 74 and 76 for the purpose of rapidly rotating the disk 36 when the arm 35 is moved out of the path of the plate 72 upon the rocking of shaft 70, as abovedescribed The rotation of said disk 36 willv cause its cam shoulder 83'to strikean antifriction roller 78 mounted on an arm 40, pivoted to the main frame at 41. The arm 40 has a projection at its upper end, which projection extends over an antifriction roll 43 on a switch controlling lever 44.. The switch controlling lever-44 is provided with provided with an insulating plate 80 which extends over the .two contact fingers 25.

When, upon the rotation of-the disk 36, the

,camming shoulder 83 strikes the antifriction roller 78, it will cause the arm 40 to rock about its pivot 41and throughthe medium of the .projection at the upper end of the arm 40 will depress the antifriction roller 43 and switch controlling lever 44, thus bringing the contact fingers 25 into contact with contact plate 181, thereby closing the motor circuits The rotation of the disk 36 -is limited in extent by the end of the elongated slot 7 5 striking against the pin 76 extending therethrough, and, as above deracribed, mounted on the disk 77 rigidly mounted on-the shaft 37; This limited rotation of the disk .36 is, however, .suflicient to hr'ingthe extended periphery of the said disk under the antifriction roller 7 8. and thus hold the motor circuit switch closed. Just prior to the completion of a single rotation of shaft 37 the camming shoulder of disk 46 will engage an antifriction roller 81 on an arm 82 which arm is rigidly mounted on the shaft 70. This engagement of the cam 46 with said antifriction roller 81 will cause said arm 82 to rock shaft 7 0, thereby again bringing the arm 35 into the path of the plate 72. This movement will arrest the disk 36, on which said plate 72 is mounted, in a position in which the antifriction roller 78 may drop into the depressed portion of the disk 36, thereby permitting the breaking of the motor circuit. The rocking of the shaft by the movement of the arm 82 will also cause the downward movement of the arm 34 to permit the pin 47 on arm 32 to again spring over its forward end. As shown in Figs. 3 and 8, there are two spring contact fingers 25; one of these controls the motor circuit while the other is intended to control a condenser which may be introduced into the circuit for the purpose of reventing a spark. when the circuit is bro en. The motor 15 drives the belt sheave 45 through the-worm gearing .66. The sheave 45 makes one revolution ateach operation of the machine and the switch 25 is automatically opened When the sheave completes a revolution by the arm 40 dropping into the cutaway portion of the cam 39 and releasing the switch arm 44. The cam 46 re-. turns the arm 34 to normal position in under the pin 47 on the member 32. I

Slack in the belt-14 is taken up when the sheave 45 is revolved by the spring belt 'tightener 48. The belt tightener 48 consists .of a sheave 49 mounted on a bell crank 50 and bearing-against the belt 14. The bell crank 50 is pivotally mounted at 51 and the opposite end to that on which the sheave is mounted bears against-the roller 52 which is mounted on a reciprocating arm 53. The arm 53 is drawn forward so as to release the belt tightener by the box cam 54 which is rigid on the shaft 37 and engages the roller 55 on the arm 53.

The belt revolves the contact members 12 by engagement with the sheaves 56 which are rigid on theshafts 20. When the contact member 12 has been stopped by one of the solenoids 11 the belt 14 of course slides on the sheave 56 until the arm 35 engages the stop 36. Each contact member 12 is provided with a stop arm 57 which engages any one of the solenoid armatures which may be moved into the path of said arm.

The contact members 12 are vertically movable intoand out of contact with the fixed contacts 23 so that the contacts will not engage while the member 12 is being rotated.

=It-nwouldnot be practicable to rotate the switch contacts 12 if they passed over all the fixed contacts 23 in such rotation as clearly this would cause an incorrect momentary lighting of the lamps. To prevent this undesirable result, the contact parts 12 are arranged to be depressed slightly during the time they are rotating so that no contacts are then made and no lamps lighted. After a rotation of the contact parts 12 is completed, they are again raised to engage the fixed contacts 23 and remain so engaged until a succeeding operation of the machine. To accomplish this function, levers connected to arms 53 as shown in Fig. 2 normally hold themembers 12 in contacting position but when the arm 53 is drawn forward by the cam 51, the arm 58 will be free to rock downwardly and allow the members 12 to lower out of contacting position. The arm 58 will permit the return of the arms 58 at the end of each revolution of the shaft 37 so that the arms 58 will lift the members 12 into contacting position; that is, after the members 12 have been set into position to light the desired combination of lamps. An alining device 60 is rigidly secured at the bottom of each of the shafts 20 in position to be engaged by the arms 58 when said arms lift the members 12 into contacting position so that arms 58 aline the contact members 12 as well as operate them.

For each denomination of the indicator, ten solenoids are provided one for each character which is to be lighted. Eaeh set of solenoids 11 is-set into a soft iron casing 61 as shown in Fig. 1. The core of each of the solenoids consist of an immovable soft iron sleeve 62. A brass rod extends through said sleeve and is slidable therein, and said rod serves to stop the arm 7 when lifted up into the path of the said farm. Rigidlv se cured to the bottom end if the brass rod 63 is an iron armature 61 which normally drops away from said solenoid "and carries with it the rod" 62 when the so enoid is not energized. Of course when t e solenoid is energized the armature 6 1 will be drawn up against the iron casingl61 of the solenoid and lift the rod 62 into the path of the arm 57 r The use of :r magneto to furnish the current passing through the cables and operating the solenoids is of decided advantage in that the magneto may be driven from a motor of any voltage of either direct or alternating current. If the cable connections were on a line circuit, the resistance thereof would have to depend on the voltage of the line circuit and it would therefore be necessary to provide many different styles of parts to accommodate the current which was desired to be used. With the magneto, however. the line current passes through the motor only and the current developed by the magneto will be of constant voltage no matter what driving voltage is used. Furthermore, the magneto furnishes a fairly low voltage current thereby minimizing the danger of transmitting it through cables and making compliance with the fire underwriters easily possible. The magneto is driven only when the motor operates and there is therefore no current in the cables except during the small period of time occupied by the operation of the motor. In fact, no

high voltage current passes from the cash register to the distant indicating mechanism as the current for operating the solenoid 30 may easily be of small voltage. The current for the lamps may be of any desired voltage but the switches therefor are all positioned at the distant indicating mecha- I11Sm.

As far as the construction so far described is concerned, it would be possible to give say a half rotation to the main shaft 26 of the cash register and then allow the mechanism to stay in such position. As the motor controlling switch would then be closed, the solenoid 30 remains energized, and the pin 17 would thereby be permanently retained in front of theflange on switch lever 34 thereby allowing a continuous operation of the electric motor. This is of course undesirable and to avoid it there is provided a pawl 73 pivoted on contrplling arm 32 which is positioned tobe rocked by the flange on arm 34 when the solenoid 30 is energized and the arm 32 moved. If at the end of an operation of the motor the solenoid 30 is still energized, the return of the locking lever 35 to.,it-s normal locking position will depress arm 31 enough so that the depending end of pawl 73 may pass over the flange on said arm 34:. This will prevent a second releasing of the motor switch until the solenoid is deenergized and the return of switch arm 32 to normal position permitted. The mechanism will then be again operative.

It is thought that the operation of the device will be clear from the foregoing description but' the circuit wiring may be briefly referred to. The motor release circuit is very simple including some generator shown as a battery on Fig. 1 which battery supplies a low voltage current through the wiring on Fig. 1 and reaching to the sole noid 30 on Fig. 2. This circuit is very simple and its operation will be obvious. As to the magneto circuits it may be said that there is a common wire 18 running from one brush to the indicator contacts 9 which are arranged in parallel. From the indicator contacts 10 multiple circuits run through the solenoids 11 in parallel and then combine toa common wire 17 running to the other brush of the magneto. These circuits are of low voltage inasmuch as they have only to control the solenoid armatures and need therefore only inexpensive insulation. The

motor circuit itself is not shown on the drawings, but clearly any convenient power wiring may be employed to drive the motor inasmuch the motor wiring has no necessary connection with the rest of the apparatus. The light circuits are shown on Fig. 2 where L indicates the line wires which in practice would usually be the regular lighting circuit of the establishment. It will of course be understood that although only one indicator is shown on Fig. 2 there would nevertheless be a plurality of such indicators, one for each bank of keys, but the circuits would be precisely the same as those shown and common line wires L may be used. The circuits from the cash register to the distant indicator are all of low voltage, the only high voltage used being for the lights and the motor, and these high voltage circuits are entirely at the distant indicator.

As to the construction of the disks for the lamps circuits, this will be clear from a study of Fig. 6. The disks 19 may be considered as divided into twenty parts circumferentially, some of which are cut away on all of the disks leaving the necessary contact exceptions. The disks are moved in steps equal to one tenth of a rotation which is clearly the distance between alternate projections 22 and the stationary contacts 23 are positioned apart a distance equal to an odd number of twentieths of a rotation so that the projections 22 which may contact with one of the stationary projections 23 will not contact with the other stationary projection. On Fig. 6 the projections 22 are marked with the number for the indication of which they are employed, for example, consider the contact marked a on Fig. 6. It will be seen by reference to Fig. 5 that the lamp 0 will be used when 0, 1, 2, 3, 5, 7, or 9 is to be indicated and therefore pro jections 22 on the proper disk in Fig. 6 are arranged so that the corresponding number of steps or tenths of rotation of the contact disk will bring the projection 22 directly under the stationary contact 0. Clearly the projections marked 1, 2 and 8 on the proper disk on Fig. 6 will be moved under contact 0 by respectively 1, 2 and 3 steps of rotation. There is no project-ion marked so that four steps of rotation will not light lamp 0. There is a projection marked 5 and this is exactly opposite contact 0 in the diagram so that five steps of rotation will bring the said projection 22 under contact 23. Without following this matter out more in detail it will be evident that all the projections are positioned to light the proper lamps and to give therefore the proper indication.

Each contact member 12 as a Whole may be considered as a single movable member or contact having divisions (the separate disks 19), each division having sub-divisions in which are differentially arranged the various contact projections 22.

Some of the advantages of the construction have been previously referred to, but the additional advantage that by the use of the magneto there is no circuit in the cables when the register indicators are moving may be mentioned. If there was such a circuit the contacts 10 and 9 would be injured gradually by sparking, but with the construction no such sparking occurs.

While the form of mechanism herein shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein disclosed, for it is susceptible of embodiment in various terms all coming within the scope of the claims which follow. For example, the generator 16 has been referred to as amagneto but clearly for s of generators or dynamos could be used: other than ones having a permanent magnet field.
